Compact Floribunda rose plant name ‘Poulpal024’

ABSTRACT

A new compact floribunda rose plant that has abundant, orange red flowers and attractive foliage. The variety successfully propagates from softwood cuttings and is suitable for year-round production in commercial glasshouses. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

Botanical classification: Rosa hybrid.

Variety denomination: ‘Poulpal024’.

SUMMARY OF THE INVENTION

The present invention constitutes a new and distinct variety of compact floribunda rose plant which originated from a controlled crossing between the female seed parent, an un-named seedling, and the male pollen parent, a rose by the same inventors named ‘Poulmanti’ described and illustrated in U.S. Plant Pat. No. 11,540, issued Oct. 3, 2000. The two parents were crossed and the resulting seeds were planted in a controlled environment. The new variety is named ‘Poulpal024’.

The new rose may be distinguished from the seed parent by the following combination of characteristics:

-   -   1. ‘Poulpal024’ has 55 to 60 petals, while the female parent has         about 40 petals.     -   2. ‘Poulpal024’ has orange red flowers, while the female parent         has light pink flowers.     -   3. ‘Poulpal024’ has a flower bloom diameter of 60 to 65 mm,         while the female parent has a flower bloom diameter of 35 to 40         mm.

The new variety may be distinguished from its pollen parent, ‘Poulmanti’ by the following combination of characteristics:

-   -   1. Petal count of ‘Poulpal024’ is 55 to 60 petals. ‘Poulmanti’         has approximately 40 to 50 petals.     -   2. ‘Poulpal024’ has orange red flowers while ‘Poulmanti’ pink         flowers.

The objective of the hybridization of this rose variety for commercial culture was to create a new and distinct variety with unique qualities, such as:

-   -   1. Uniform and abundant orange red flowers;     -   2. Vigorous and compact growth when propagated on it's own roots         as well as from grafting;     -   3. Suitable variety for production in 19 cm pots;     -   4. Superior disease resistance;     -   4. Attractive, dark, glossy foliage.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poulpal024’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated the seeds from the aforementioned hybridization and conducted evaluations on the resulting seedlings in a controlled environment in Fredensborg, Denmark.

‘Poulpal024’ was selected by the inventor as a single plant from the progeny of the hybridization in June 1998.

Asexual reproduction of ‘Poulpal024’ by cuttings and traditional budding was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in April 1998. This initial and other subsequent propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poulpal024’ are true to type and are transmitted from one generation to the next.
